Patented Dec. 24', 1912.

screw with the hand, and especially to a' simple-form of such devices 'such as w1ll' hereinafter be fully described.

The objects of the invention are to generally improve devices of the character mentioned and to provide a screw holder for screw drivers whichemay be temporarily applied to any ordinary screw driver without making any change in the construction of the screw driver bit and which may. be readily and quickly removed from the sore driver when it is not needed. Further objects are to provide a'device of the character described which may be stamped from sheet-metal and thus be both easily and cheaply made, and which will be effective and convenient in use.

These objects,'.together with other objects apparent to those skilled in the art may be attained by the construction illustrated in the accompanying drawings, although the invention may be embodied in other forms, the construction illustrated being chosen by way of example In the drawings Figure 1 is a perspective view of a screw driver bit in engagement with a screw, and a screw holder embodying my invention in proper position to hold said screw. Fig. 2 is a perspective view ofthe auxiliary clamp for use on the screw holder. Fig. 3 is a perspective view of the screw holder with the auxiliary clamp attached. Fig. 1 is a plan view of the blank of sheet metal from which the screw holder is made. Fig. 5 is an end elevation of the screw holder, showing a screw driver bit and screw in dotted lines. Fig. 6 is a side elevation of the screw holder. Fig. 7 is asectional view on the line 7-7 of Fig. 5.

Throughout the several views similar refarts.

The screw holder'is stamped rom sheet metal, the blankfrom'which same is formedv being illustrated in. Fig. 4. Thehead 1 is forming the first bit en aging tangs 3 and bending same downwartfi I lines 4. At opposite sides of the head 1 the integralspring arms 5 are provided which i are bent at 6 into parallel," spaced position with reference to each other, at right angles of the arms 5 are inwardly bent along the dotted lines 7 ,and the extreme ends of said arms are properly formed for engagement with a screw, such formation preferably cony along the dotted to the plane of the head 1. The free ends sisting of the screw holding notches- 8.

Stamped out of the upper portionsof the arms '5 the second bit engaging tangs 9 are bent inwardly along the dotted lines 10. Formed integrally with the arms'5 and adjacent the free ends thereof, but above the lines 7 the third and fourth-bit engaging tangs 11 and 12 are provided, the tangs 11 being bent substantially at right angles to the planes of the arms 5, and the tangs 12 being bent farther inward than the tangs ll.

It will be understood that the device should-be made, of spring material sothat the'spring arms 5 may securely hold a screw between their opposed free'ends. The various tangs mentionedp however, should be sufficiently bendable so that the device'may be adjusted for use on the particular screw driver for which it is intended. Such adjustment is accomplished by bending the tangs 3 until their free ends engage the edges 13 ofthe screw driver bit 14: while the tangs 9 should be so bent'that their free ends engage the Hat sides 15 of the bit. The

some support with reference to the bit 1 1 the tangs 11 should be bent'inwardly' until they engage the edges 13 and the tangs 12 should be so bent as to somewhat loosely engage the sides 15 in order that the arms 5 may be free to properly hold a screw between them. From an inspection of Figs. 1, 5 and 7 the relation of the various tangs when in their proper positions with reference to the bit will be readily understood.

In practical use the screw holder may be,

carried in the pocket or kept in other convenient location and applied to the screw driver bit when needed, the-screw driver at other times beingentirely' free from annoyapplying the holder to the bit it is only mg attachments or special formation. 'In

necessary to insert the point of said bit into the slot 2 and push the same down between thevarious bit engaging tangs into substantially the position shown in Figs. 1 and 5. A screw, such as illustrated at 16 may then be readily inserted between the free ends of the spring arms by forcing the same in from the edge of the device, as will be clearly understood from Fig. 5. When the screw has been received into the notches 8 it will be firmly held by the arms 5, and the point of the bit 14 may then be entered into the slot of the screw, whereupon the screw will be firmly held and may be entered into the wood or other material into which it is to f outwardly to form the spaced ears 18 be-- tween which and to which is pivotally connected the eccentric lever 19 provided with the thumb piece 20. In applying the clamp to the screw holder the band is merely slipped over the free ends of the arms 5 and brought to a position substantially midway between the head 1 and the free ends of said arms, as'shown in Fig. 3. The portion 21 of the hand then engages one of the arms 5 and the opposite portions 22 engage the other arm. The band should be made of ,such size as to snugly fit upon the arms and "to thus .frictionally maintain its position when the device is in the unclamped condition. The unclamped position of the lever '19 is illustrated in Fig. 2. To clamp the 1 position illustrated in Fig. 3, whereupon the eccentric portion of the lever 19 will engage ward the other arm 5, thus increasing the clamping force of the two arms upon the screw, as will be well understood by those skilled in the art.

A consideration of the above description, with the drawings, will disclose how very readily and cheaply a screw holder of my invented construction may be made. WVhile being a very useful and practical tool or attachment it may be placed upon the market at slight cost and at the same time will prove thoroughly efficient and practical in every respect.

I claim 1. A screw holder for screw drlvers comprising a head provided with a slot, integral first tangs at the ends of said slot, integral spring arms at opposite sides of said head extending at right angles to the plane of said head and parallel with each other and their free ends adapted to engage the head of a screw, second tangs stamped from the upper portions of said spring arms, and integral third and fourth tangs formed on said arms intermediate their ends, said slot adapted to receive a screw driver bit, said first and third tangs adapted for engage- .ment with the edges of said bit and said second and fourth tangs adapted :for em gagement with the sides of said bit.

2. A screw holder for screw drivers formed from a blank stamped from sheet metal, said blank comprising a head portion provided with integral tangs adapted to be bent out of the plane of said head portion to form a screw driver bit receiving slot, integral arm portions extending from opposite sides of said head portion and provided .with integral tangs stamped from the bodies of said arm portions and with other integral tangs projecting from the edges of said arm portions.

In testimony that I claim the above, I have hereunto subscribed my name in the presence of two witnesses.
